The YN-568EX is the latest flagship TTL flash from YongNuo, and the first flash unit from a Chinese manufacture to feature High Speed Sync (HSS) allowing camera shutter speeds up to 1/8000th of a second.

Released just in time to team up with the new, and already very popular, YN-622C ETTL and HSS enabled radio triggers for off camera flash use. Currently available for Canon cameras, though a Nikon version is sure to come [EDIT – now available].

YongNuo have really come a long way since their first TTL flash just a few short years ago, and the new YN-568EX is now quite a nice flash unit coming much closer to the original Canon/Nikon and other 3rd party Japanese flashes, and at a considerably lower price.

The main things lacking compared to the higher priced offerings are mainly just the wireless master control (which is not really needed so much anymore), lack of USB port for firmware updates, and no external battery pack port. The omission of a battery port really being the only thing that may be a deal breaker for some, though the fast standard recycle may counter that to some degree. And for those looking for TTL slave flashes, compatibility with non YongNuo radio triggers may also be an important consideration.

Good Power – only around 3/10th of a stop off the top end Canon/Nikon alternatives

Fast Recycle – from 2 – 3 seconds at full power

Both Canon & Nikon Optic Wireless slave functions built in.

S1 & S2 simple Manual optic slave – for regular or TTL pre-flash

Sound Beep – indicates recycle ready and low exposure

+ or – 5 stops of Exposure Compensation in ETTL

1/3rd and 1/2 stop Manual power adjustment, even both methods combined

Compatible with Canon’s built in Flash Control Menu

2.5mm Sync Port – Instead of the troublesome traditional PC sync port

Full Head Swivel 180 degrees left and right

No distance scale in Manual mode

No Auto exposure mode (Auto is the old method before TTL)

No weatherproofing

In Use –

The YN-568EX is very simple to operate and the TTL exposures and HSS have been working exactly as expected. Also teamed up with the YN-622C off camera triggers the 568 is working spot on and allowing all features. Power is about is a little below the Canon 580ex, and recycle time is considerably faster (more detail on these below). Buttons and controls are easy to operate (no more mushy buttons) and the recycle beeper (particularly in ETTL) is also really handy. Overall the YN-568EX is a nice flash to use.

Flash Body –

New Body Design

Instead of just adding HSS to the previous YN-565EX TTL flash model (which was a close copy of the Canon 580EX II body and LCD screen), YongNuo have designed a completely new original body for the 568EX, and its mostly all the better for it. It has a large clear LCD and nice solid plastic control buttons, no more spongy rubber ones. The body had a nice square shape with matt textured finish, and its actually all just a little bit smaller than the previous 565/580EXII.

Flash Head Full Swivel

The flash head also now has a full 180 degree swivel in both the left an right direction, which can save a lot of hassle and frustration. The head is tighter to click into positions, which means it will likely support modifiers and softboxes etc better without moving around. The only problem I have with this is when using pass-through hotshoes like YN’s on own YN-622C ETTL trigger, it puts even more stress on those if swivelling the flash head constantly.

Flash Head Size

The flash head as shown above is very similar in size to the 565/580EXII, with the 568EX being just a little smaller in width and height. So 580EX/II Stofen caps and modifiers should at least still fit over the 568EX head, but they may need a little extra packing or gaffa tape to hold them in place. Its great that YongNuo have an original design now, but one thing that would be very convenient is to retain the head shape of the current Canon or Nikon flashes for this reason.

Less Locking Ring Space

Also a slight step backward from the 565/580EX II body design is less finger room to access the locking ring, its fine on most cameras, but again on the 622C triggers or regular flash stand, less finger room makes it harder to get your fingers in there to secure the flash tightly or get it undone again. Its not really obvious in the image above, but there is considerably more room around the locking ring on the 565/580EX II (shown right).

LCD & Functions –

Large Clear LCD

The 568EX has a nice large clear LCD making it easy to see and adjust TTL exposure compensation and manual power levels. Image left below shows ETTL set with + 4 and 1/3rd stops of exposure compensation. Image right shows Manual power set at 1/2 power + 0.7 .

Simple Controls

Most of the Controls are very simple and straight forward, the 568EX user manual even states at the beginning with a Quick Start guide – ” You can understand the function of each button by pressing them and observing the displayed content”, which is exactly the simple and intuitive operation you want to see.

The exception to this is mainly for the Canon/Nikon Optic Wireless slave function, which is easy enough to select by holding the MODE button for few seconds, but then 2 buttons need to be pressed at the same time to change channels and groups there. The other exception is selecting the custom functions which also requires a 2 button press. Arrows marked between the buttons do help as a guide to the combinations though. Overall for general use the 568EX is very simple to operate and previous setting are automatically remembered.

5 Stops of Flash Exposure Compensation in TTL

Exposure Compensation is adjusted very simply in full stops via the left and right arrows, and the the up and down arrows allow fine adjustment in 1/3rd stops. A big advantage though is the 5 stops of FEC adjustment, where Canon usually only provides 3 stops at most.

This is likely more of an advantage with off camera use with the YN-622C triggers for creating larger ratios, or reducing bright rim lights etc, as the FEC set on the flash will add to the ration set from the camera

If adjusting FEC via the camera you still only have the 2 or 3 stops originally provided there, if FEC is set on the flash it overrides the cameras FEC setting, not adding to it.

Manual Adjustment in Full, 1/2 & 1/3rd Stops

Manual power adjustment is made in full stops via the left and right arrows, and 1/2 and 1/3rd stop fine adjustments via the up and down arrows. By default 1/3rd and 1/2 stop adjustments are offered at the same time, which is really quite handy, but you can also select just one or the other in the custom settings.

One minor thing I’m not keen on is the power adjustment scrolls around in a loop instead of stopping at full power and minimum power. So from full power it continues straight on to minimum power and upward again. Again this mainly concerns off camera use, but it means you can’t easily adjust the flash inside a softbox for example just by feel, you really need to see the LCD to know where the power is set.

Power Output –

We have heard some slightly varying reports regarding the power output of the 568EX, but this unit appears to be around 0.3 of a stop less powerful than the Canon 580ex. That puts the 568EX just a couple of tenths above the 430exII, which is reasonably consistent with most reports. It’s also about 0.3 stops above our manual YN-560 units which are similar to the 565EX. Results do fluctuate a few tenths though anyway, we noticed this particularly with the YN-560.

The way we tested the power was using a shoot through umbrella (flash zoom set to 35mm) which removes any advantage gained by having a slightly tighter beam, or less even spread of light (ie more of a hot-spot in the centre). The bare flash results were a little closer between the YN-568 and Canon 580EX in the centre of the frame, which just shows the 568 had a slightly tighter or less even light pattern at the same zoom setting.

Power Output HSS –

The YN-568 is the first HSS enabled flash from YongNuo (or any Chinese manufacturer) so we were very interested to see how well the 568 would fair, and results turned out to be quite comparable to the Canon units.

HSS power output as we have found previously with Canon flashes can vary significantly from one flash unit to the next, we have 2 identical 580ex’s and one puts out a stop more power than the other in HSS, and that is not uncommon to other peoples experience as well. But the YN-568EX in HSS is about the same as the lower powered 580ex, which is quite reasonable considering its overall power is down a little on the 580ex to start with.

What does this mean is practice? – HSS was mainly designed to allow fill flash in bright ambient light, at higher shutter speeds though, which in turn allows wide apertures for narrow depth of field portraits. People will often say you loose 2 to 3 stops of power as soon as you go into HSS. This is true, but the way HSS was designed to work is that you open the aperture a stop to compensate for every stop of shutter speed increase. That means the ambient exposure does not change, but the flash exposure is down around 1.3 stops of power. That is similar then at any shutter speed right up to 1/800oth provided you open the aperture to match. For off camera use a second flash at least helps to regain a stop of that power back.

Recycle Time –

The YN-568EX standard recycle time is pretty fast, between the 430exII and 580exII, which makes sense as the power is in that area to. Approximate recycle times using rechargeable Energizer 2500mAh NiMH batteries –

Full power – 2 – 2.8 seconds

1/2 power – 0 – 0.5 seconds

1/4 power – pretty well instant

Going by the ready light full power recycle is most often around 2.8 seconds though it can fluctate from as low as 2 seconds to 3 or 4 sometimes. To run of 20 or more pops at a continuous rhythm around 4 second intervals would be needed to keep the recylce consistent. Ideally atleast half power (or less) would be used in continuous shooting though and 2 second intervals at 1/2 power is enough to allow shooting continuously for quite a while. 1/4 power is pretty well instant.

These times are fairly good, and fine for people that don’t generally relly on external high voltage battery packs (which the 568EX does not support anyway), but the pack option would make a considerable difference. With an inexpensive Pixel pack and the 580ex we can easily get consistent 1-1.5 second full power pops over many shots, and 1/2 power is consistently ready to go all the time. Overheat becomes the only limiting factor then.

In general though the 568EX recycle is very good when you consider previous third party Japanese flash option like the Sigma and even the current Nissin Di866II is much slower, even the original Canon 580ex take 4 to 5 seconds which feels like an eternity compared to the 568EX.

Over Heat Protection –

The YN-568EX has an Over Heat Protection mode which saves the flash from being damaged by excessive heat built up, though I was able to fire off 60 continual full power flashes (as soon as the ready light came on) before the flash went into the protection mode to cool down for a few minutes. That is much better than the previous YN-560 units which would reach thermal shut down after just 20 full power shots.

Sync Port –

The YN-568EX has only one external port, though its a very welcome standard 2.5mm mini jack sync port, instead of the traditional and problematic PC sync ports often used in flashes, and also still in most camera bodies. We wish they would all adopt the standard 3.5mm mono audio jacks, but 2.5mm is a good start, and much better than the traditional PC port. The Sync port is used to connect the flash to a camera or radio trigger for basic manual firing.

Locking Ring –

The Yn-568EX also uses a simple standard locking ring on the foot, unlike the complicated lever locking mechanism now found on Canon/Nikon and some other third party flash units. This likely saves cost, but it saves hassles and expensive repairs as well, so a few seconds extra to lock the flash down is no problem.

Focus Assist Light

The AF light on the YN-568EX is the same as used previously in the YN-565EX flash unit and now the YN-622C radio triggers. Its reasonably basic for centre focus point use only, but it is a pretty bright and sharp laser which projects a grid contrast pattern within a small circle, which is easily big enough to cover the centre focus point. That is provided you are at least a meter or so from the subject, otherwise it may tend to be a little high. At longer distanced its closer to centre, and I found it locks on focus well from quite a distance. It’s stronger than the Canon light but it doesn’t have the long vertical pattern, or horizontal patterns for the other focus points.

Sound Prompt / Ready Beep –

This is a very handy feature that even the Canon flashes still don’t have. Even the inexpensive manual YN-560 flash has this option of a beep sound to let you know when the flash has recycled and is ready to fire again.

But even more useful now with TTL and HSS is another beep sequence which tells you if the flash had enough power to expose the image correctly in ETTL. This is great if you have the flash off camera in a softbox etc where you can’t see the ready light. You know before even checking the camera LCD, that the image was underexposed due to lack of power and not a TTL metering mistake etc. And also if you took a shot before the flash was ready.

Custom Functions –

The YN-568EX offers a number of custom functions, a few relating to various power of times, FEB sequences, AF assist light disabled etc.

One I really like though is E2, which is an instant Power ON or OFF for the flash, no more holding the power button for 3 seconds to get started!

Battery Compartment –

The battery compartment has an unusual layout and you have to note which direction the batteries go in. That’s not really any big issue though and its fast a simple to load otherwise. The door slides on a nice track which is very quick and easy to open and close without any special concentration.

Slave functions –

The YN-568EX has both Canon & Nikon Optic Wireless slave functions built in. This means it will operate as a full TTL/HSS slave unit off camera, controlled by the master (or commander) units built into all recent Canon and Nikon DSLR camera bodies (as well as external master units like the ST-E2 and SU-800). This is the near infra-red wireless system often using flash pulses from the pop-up flash on the camera body to communicate. It requires line of sight and can have issue with bright light. See the YN-622c radio triggers below for a more foolproof option.

The YN-568EX also has S1 & S2 simple Manual optic slave mode for regular or TTL pre-flash. This is a basic optic slave that will just fire the flash in manual with no remote control. This is still very handy though as any other manual or TTL flash can be used to simply trigger the 568EX, in sync, off camera.

YN-622C Radio Triggers –

They YN-568EX is available just in time to team up with the new inexpensive, and already very popular, YN-622C ETTL and HSS enabled radio triggers, for off camera flash use. The 568ex being the most economical and compatible HSS enabled flash currently available.

As you would expect the 568EX is completely compatible with the 622C and allows all options available through the Canon Flash Control Menu. That allows remote control of up to 3 groups of flashes in ETTL with ratios, or Manual power control in 1/3rd stops.

As you change settings through the camera menu you can also see those settings changing on the flash LCD, its almost feels like a little bit of magic there.

Although limited in some ways by the constraints of the Canon flash menu options, this is a pretty impressive system for the price. So far its shown to be mostly trouble free and reliable, and pretty smooth in its operation. For more details on how the 622C functions its best to see the full YN-622C Review here.

Probably the main advantage I found with the 568EX is the recycle and low exposure sound prompt beeping. With the flash off camera and possibly hidden in a softbox or umbrella, the beep lets you know when the flash is ready, but also when there is not enough power to expose the image properly in ETTL. That can be very handy with the lower power of HSS, once you get the warning you know straight away that you will need to move the light closer or open the camera aperture to get a better flash exposure.

The main disadvantage again is the lack of external HV battery pack option, as with HSS off camera you are often basically shooting at full power. A second flash ganged together with both units set at half power can also reduce the recycle time considerably, and also allow a lot more shots before overheating. The reality is though you often want to bump both flashes up to full power using HSS like this anyway.

The YN-568EX is the most economical HSS enables option available for the YN-622C though, and apart from the omission of external battery port it works very well in combination with them.

Compared To –

There are no other HSS enabled flashes that will currently go head to head with the YN-568EX on price alone, most other options are around $100 more, which is quite considerable when we are talking around $180 vs around $280 for the Canon 430EX II, Nissan Di866, some Metz units, Sigma (which are quite dated now), and the Phottix Mitros flash which is just around the corner.

I’m sure a lot of people though, especially those looking for a first on camera flash, will be tossing up whether they should pay the extra for a Canon flash, or possibly even buy one second hand one at similar prices.

Canon 430EX II –

The 430EX II is really the closest Canon flash in terms of price, power, recycle time, (and lack of external battery port). The YN-568EX for all its extra size is only a few tenths of a stop ahead in power, and recycle times are fairly similar.

Reliability –

YonNuo flashes (unlike their radio triggers) have had some well documented issue with reliability in the recent past. Though the 568EX is the first release I have not seen any failures reported so far (touch wood), so there is hope improvements have been made this time. We will certainly follow this closely as more are in circulation.

The safe way to ensure you get your moneys worth though is to be sure the seller offers a reasonable warranty period and where possible purchase from a local seller so that turnaround is not weeks or months if there is an issue or exchange required. For People in the USA or UK Amazon has been found to be a good option due to their fast exchange service and still competitive prices.

No USB Port –

Like the recent YN-622C radio triggers, YongNuo have chosen to keep the price low with the 568EX leaving out a USB port for future firmware updates. So there is no guarantee future camera bodies or even radio triggers will be completely compatible without any issues.

This is just one of those considerations you have to weigh up. The Nissin Di866II and Phottix Mitros etc have the USB port but cost more initially, while the 568EX like the 622C is priced to make the most out of now. If you know you’re going to be in this for a while, spending a little more now may actually save some money in the future.

Compatibility –

Note –
There were 2 software bugs in the initial release which have been rectifiedin units from November 2012.
40D, 50D, 60D, and 7D – Experienced an overexposure in ETTL and HSS at 1/250th second shutter speed.
20D, 30D and 5D – the YN-568ex did not work at all directly on the camera hotshoe.

Included –

YN-568EX Flash Unit

Padded Case

Mini Base Stand

Instruction Manual

Summary –

If you’re looking for an inexpensive first on-camera flash unit the YN-568EX is certainly a nice flash. I think back to the Sigma DG super which was the common budget flash alternative just a few years ago, and the 568EX is worlds apart without any of the major quirks and considerably cheaper still. My main considerations would be compatibility with future cameras and reliability, otherwise the flash itself I’m sure many people will be very happy to own as a first flash unit or back up.

As an inexpensive TTL/HSS radio slave flash alternative the main consideration again would be compatibility. YongNuo already have a first good option with the YN-622C TTL trigger, but other brands with slightly more serious offerings already have compatibility issues with YongNuo flashes, and as things get more complex and competitive there will likely be less compatibility between these third party brands, so its more like buying into a system which takes some consideration. Otherwise the 568EX again as it stands (apart from the lack of battery port) is great HSS enabled remote slave unit at the best price available so far.

Thanks, good point! I completely missed that. To be honest the scale is not something I personally take much notice of anyway, as modifiers, snoots, gels etc all take a toll on the stated distance, on camera its usually bounced.

I’m not sure why they would leave it off though, as it seems like a relativley simple device.

Good, informative article. Thanks for doing that research! One question: The “issues” with third-party radio triggers was sort of vague. Could you be more specific? Will the unit work with the Pocketwizard Flex TT5 (which I own) or is it one of those things where it might or might not?

Thanks Daryl, I haven’t tested with the PW TT5, but the previous YN-565EX and other YN TTL flashes do not work with those, so its quite likley the 568EX won’t either. But even if it does appear to work ok now you have to consider that may change with future PW firmware updates. Also the 565EX is compatible with the current Pixel Kings for example, but there are still a number of isolated cases saying they don’t work together at all, and also when issues arise its no surprise to hear a YN flash is involvled. So in that respect I would be wary of relying on compatibility with PW or other third party TTL triggers. The Canon 430EX is pretty solid with the TT5 and you could likely pick up some of those for not much more second hand if needed.

I bought the Altura TTL speedlite for Nikon and I have no complaints. However, I found a great deal on a new 568EX for Nikon and couldn’t pass it up, $85 and they only had one. I can’t wait to compare the two and I’m very new to DLSR, bought my D5200 nine months ago.

I read a lot about the basics, manual mode, aperture, shutter speed etc, and shot a lot of photos. Then I started reading a couple of books about lighting after I pretty much knew how to operate the camera, and what doesn’t work, then bought the Altura. Wow, what a difference it makes.

Many of the examples use two lights so hey, for the price I went for the 568. I do have the Altura triggers though they are not OC TTL. I never plan to be a pro as in a portrait photographer or have a studio for paid work, it’s just a hobby.

Thanks for all of the good info and I seen your comments had been disabled, wow, bummer. I’ll report back shortly, and sometime after I’ve had the 568 for a long time with how it’s holding up. I had researched forever about if the 622N-TX and 622N trigger would work with an Altura TTL flash with no luck at all.

I finally found an Amazon review on the 622N-TX that says it does, though it may be a stop or so darker. He said he did non-rigorous testing. He may have been using HSS, not sure. I had been reading reviews on everything but the TX only…kits with triggers etc didn’t have that info. I plan to get the 622N-KIT soon and I’ll test it on both speedlites.

As you can see I’m having a ball and do appreciate all of the info on 3rd party equipment etc. If I had bought a SB-800 I’d never be able to read all of the info, not so with the Altura or Yongnuos. Thanks again.

I have a Nikon and the 568EX II is Canon so I assume you want a Canon flash.
There is a YN-600EX-RT that does HSS and can be used as master unit to trigger another YONGNUO YN600EX-RT or Canon’s 600EX-RT, and live display the flash groupings of slave unit and recycling information. As far as I know there isn’t a Yongnuo master capable flash for Nikon yet, that’s why I remembered this. One of the reviews says it is a near perfect clone of Canon’s 600EX-RT flash.

Last night I came across a D7100 body in a local photography group for $395 so I’m getting it, can’t pass it up at that price. My D5200 doesn’t do HSS and doesn’t have commander mode, but the main reasons I want it is the focus motor (already have a couple of lenses that need it) and the many other added controls and features.

I really studied all of the models before I bought one and planned to upgrade before the D5200 lost too much value. With the new flashes and D7100 I have a lot to learn, but that is why I’m doing it, not for profit.

And you’re right, I seen the 500EX and forgot all about it and I got my 568 for the price of the 500. Getting the D7100 means I’ll have to hold off on the 622 kit for a little while, at least until I sell my 5200, but I do have the Altura trigger so it’s a start.

Ok, maybe this is a dumb question but I am having trouble finding information for the full frame/half frame setting (Fn NO 03) on the 568EX for Nikon. My 568EX zooms from 24-50 with my 18-55mm lens. When I seen the full/half setting I assumed that would make it match more closely but It doesn’t change anything on the display. I’m aware 24-50 may be ball park numbers for wide and 50mm zoom or so.

The Altura TTL flash goes to 18 and more closely follows your current zoom up to 180mm. The Altura does have ranges, it does not count 18, 19, 20 (but it does go 18, 20, 24, 28, 32, 35, 38, 42, 46, 50, 55 with the 18-55mm lens). With the camera on a tripod you can see your approximate zoom right there. It hits a ball park number that works for a given range of zoom. The Altura also displays aperture and ISO.

The 568 only goes 24, 28, 35, 50, that’s it, and only displays aperture, no ISO. I know ISO is displayed on the camera (D7100 has a small display for that), but you have to turn on the screen for a D5200 (eats battery faster). Both cameras display ISO in the viewfinder, still the Altura puts it right up in your face which is handy.

I’ve tried the 568EX on a D5200 and D7100 and it just doesn’t track the actual zoom as well, which is fine if that is normal and it works ok.

What is the full/half frame setting on the 568EX? I assume it changes the amount of zoom for the flash to better match the camera, but that is not shown on the display which doesn’t mean it isn’t making changes internally. I’m not unhappy with the 568EX, I’ll be the one using it and just want to understand it. I’m sure my wife is going to love the Altura on her D3300 (she doesn’t want my like new D5200).

Thanks again for all of the info and I hope someones finds this info useful.

The YN-568EX are originally based on the Canon style flashes, which only zoom in 24, 28, 35, 50 etc graduations. Even the current top end Canon 600EX-RT is still like this.

Being a Canon user I didn’t even know until after recently purchasing an SB-700 that Nikon flashes zoom in much finer graduations when following the camera lens.

So yes that’s the way its intended to function. The full/half frame setting just zooms in a little tighter to match the narrower field of view or crop sensor cameras. I don’t think that has any change to the zoom setting shown on the LCD display, though it should be zooming to match the cameras field of view.

I have just received a YN568EX11 and the rear screen shows M continiually in the zoom window and I cannot fins how to take the M (manual) away so that the flash will work on Auto. Also how do you get to the custom functions?

Put the camera in manual mode, turn off auto ISO and you’ll have full control. If you’re shooting people in TTL and want proper skin tone do about a +1 stop compensation on the camera because TTL exposes for medium gray.

Hi,
I have just purchased a Yongnuo YN568EX-Nikon.
I note that that the approved batteries are, – Power supply – 4×AAsize batteries (Alkaline or Ni-MH are usable).
I would like to use “AA” Lithium batteries for better & longer performance, are Lithium batteries useable in this flash or not??

I didn’t really understand from the review about the TTL compatibility (Nikon – Canon). Maybe I missed it. Can I tell just by looking at the package if it is compatible with Nikon or Canon?
YN-568EX II is for Canon and YN-568EX is for Nikon?
Some Yongnuo products have a -C and -N suffix to show compatibility.

Does anyone know if Yongnuo’s service/support for the YN-568EX has improved? I have a YN-568EX that six-months after purchase will power up, all the controls work, but after firing once it freezes. At the time I contacted Yongnuo and they were less than helpful. Looking for a solution that doesn’t involve paying Yongnuo any more money to have them fix a faulty unit.

One thing I learned yesterday is to not keep the Yonguo wireless commander on the camera if it’s off. I’m not sure if the Canon version behaves the same way, but I wreaked havoc (lol) with my exposure in Av mode. Took me awhile to figure out what was wrong. I’m used to just turning off my flash and leaving it on the hotshoe, but do not do that with the wireless head.

Why is it that “the flash exposure is down around 1.3 stops of power” in HSS? It was previously mentioned in the same paragraph that you “lose 2 to 3 stops of power as soon as you go into HSS”. What am I missing?

I have a Nikon D750 and the data exchange between the yn 622n-tx don’t work and yn622 did not work (power 1/1 1/2 1/8….1/128) except for the zoom very disapointed.And sometime i have to tight and twist the TX on the hotshoes cause nothing work.

I have received two 568EX from amazon and i have some problems already. In HSS mode when i go past 1/250 the flash does not fire in “auto” mode anymore it does not go full power but it’s way brighter then the correct exposure i got at 1/250 and below. I have compare it with the manual mode at 1/128 and it’s approximately the same power output. But Sometimes it works perfectly, the flash exposure does not change when going above 1/250 and everything is just so fine and perfect. Then it goes crazy again and bye bye auto power beyond 1/250. It’s so frustating knowing that it’s working properly, sometimes.. Will get them back to amazon. (same goes in slave mode, sometimes the exposure is so good and i can compensate easily with the ambiant light, and then, poufff, all the flashes go crazy and go unreliable..) Anyone having those issues, am on a Nikon D600, an old one, maybe it’s the Nikon that is dying.

This flash is a warrior and much better than any recent YN releases, which is weird, how can old yn flashes be better than the newer ones? The only complaint I have is just that the battery door is not great.
